5-LO

5-LO

Abbreviation for 5-lipooxygenase.

ALOX5

A gene on chromosome 10q11.2 that encodes a member of the lipoxygenase (LOX) family of non-heme iron dioxygenases, which are involved in the production and metabolism of fatty acid hydroperoxidases.

Molecular pathology
Mutations in the ALOX5 promoter region lead to a reduced response to antileukotriene drugs used for asthma, and may also be linked to atherosclerosis and several cancers.

In the second poster, "A Role for the 5-LO Pathway in Allergen-Induced Airway Infiltration of Eosinophils and Neutrophils in a Murine Model of Asthma," lead author Lyn Libertine of Critical Therapeutics and her colleagues show that ZYFLO plays a key role in inhibiting the migration, aggregation and adhesion of eosinophils and neutrophils in response to leukotrienes, which play an important role in inflammation.
